Which closure device uses a non-absorbable nitinol clip to mechanically seal the arteriotomy?

• A. Starclose closure device
• B. Perclose closure device
• C. Angioseal closure device
• D. Mynx closure device

Answer: (A)

The key idea is how the arteriotomy is sealed: by mechanically closing the puncture with a clip instead of sutures or plugs. The StarClose closure device deploys a small nitinol clip that grasps and approximates the two edges of the arterial puncture, effectively sealing the arteriotomy. Nitinol is a shape-memory, durable material, so the clip stays in place and provides permanent mechanical closure rather than dissolving. This differentiates it from other devices: sutured closure uses stitches to close the puncture, collagen-plug systems seal with a plug and anchor, and polymer-based sealants create a temporary extravascular seal that typically resorbs. So, the StarClose device is the one that uses a non-absorbable nitinol clip to mechanically seal the arteriotomy.
